Do you need TR19 inspection in Ayot Green?
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
Keep an eye out for these warning signs:
- Surveys needed before quoting a full clean
- Parts of the system left out of past cleans
- Post-clean verification after another contractor’s clean
- Systems cleaned on a calendar with no measurements
School kitchens, at schools like Monk's Walk School for example, are typically cleaned in the holidays so no lunches are lost.

TR19 inspection in Ayot Green
Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, which is why measurement matters. We give your risk assessment measured figures rather than guesses. If you’re dealing with missing TR19 certificates or history and cleaning intervals that may not suit the kitchen, we can put it right, from pre-clean surveys, insurer audits and deposit thickness tests onwards.
For a kitchen in or near Ayot Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
FAQs for Ayot Green
Which environmental health team covers Ayot Green?
That’s Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Ayot Green. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you work in villages like Ayot Green?
Yes, Ayot Green is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
At what point does grease need cleaning?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
How often should a kitchen extract be inspected?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a morning or less for one kitchen, more where there are several systems. Seeing the system in photos first means the trip to Ayot Green can be planned properly.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload

Kitchen extracts in Ayot Green
There are about 37 cafés, restaurants and staff canteens and about 7 takeaways within about 1.5 miles of central Ayot Green, according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Ayot Green sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Ayot Green get their food hygiene inspections from Welwyn Hatfield council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Historic houses near Ayot Green, such as Digswell House about 1.1 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Volunteers running a hall kitchen near Church of St Peter, or anywhere in Ayot Green, may not know when the extract was last cleaned, and a grease test settles it.

What TR19 inspection can’t fix
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Heavy deposits found on test, which still need cleaning
- Fire safety duties beyond the extract system
- Installation problems, which fall under design guidance such as DW172
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.
What we work on in Ayot Green
- Pre-clean surveys
- Access surveys
- Deposit thickness tests
- Insurer audits
- Post-clean checks
- Wet film thickness tests
Between visits
To keep the system working properly between visits:
- Have the latest report ready for insurance renewals
- Keep to the recommended interval
- Keep canopy edges and gutters wiped down
- Mention new equipment or longer hours at the next test
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
Close the access gaps found during inspection, so grease is not left building in hidden parts.
What the work involves, part by part
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
